Supreme Court ruled that past disability benefits remain valid if guaranteed by law for over ten years. The court held that new control tests cannot retroactively revoke benefits already established under old regulations. This decision clarifies that procedural changes do not invalidate previously granted rights. The court dismissed the social insurance agency's appeal and restored the pension rights. The judgment emphasizes legal certainty and the protection of acquired rights in social security matters.

The Supreme Court of Poland restored the applicant's right to a disability pension and rejected the social insurance agency's appeal. The applicant had received a pension for over a decade before a new law changed the classification of such benefits and ordered a control medical examination. The court found that the agency lacked legal grounds to order this examination after ten years and to stop payments based on its results. Consequently, the court ruled that the original decision to grant the pension remained valid and could not be retroactively revoked by the new regulations.
